Examples of the non-crop land in the present invention include athletic fields, empty lots, railroad edges, parks, parking lots, road edges, dry riverbeds, lands under a power line, residential lands, and factory sites.

The crop cultivated in the crop field in the present invention is not limited as long as the crop is a variety generally cultivated as a crop.

The plant of the above-mentioned variety may be a plant that can be produced by natural crossing, a plant that can be generated by mutation, an F1 hybrid plant, or a transgenic plant (also referred to as a genetically-modified plant). The plant generally has properties such as obtaining of the tolerance to a herbicide, accumulation of a toxic substance against a pest, suppression of the susceptibility to a disease, increase in the yield potential, improvement in the tolerance to a biotic and an abiotic stressors, accumulation of a substance, and improvement in the preservability and the processability.

An F1 hybrid plant is a first-generation hybrid obtained by crossing varieties of two different strains, and generally has a heterotic property with a trait superior than that of either of the parents. A transgenic plant has a foreign gene introduced from another organism or the like such as a microorganism and has a property that cannot be easily obtained by cross breeding, mutagenesis, or natural recombination in a natural environment.

Examples of the techniques for producing the above-mentioned plants include conventional breeding techniques; genetic engineering techniques; genome breeding techniques; new breeding techniques; and genome editing techniques. Conventional breeding techniques are for obtaining a plant having a desirable property by mutation or crossing. Genetic engineering techniques are a technique for imparting a new property to a target organism by extracting a target gene (DNA) from another organism (for example, a microorganism) and introducing the target gene into the genome of the target organism, and are an antisense technique or an RNA interference technique for imparting a new or improved property by silencing another gene present in the plant. Genome breeding techniques are for improving breeding efficiency using genomic information, and examples of the genome breeding techniques include DNA marker (also called genomic marker or genetic marker) breeding techniques and genomic selection. For example, DNA marker breeding is a method in which a progeny having a target useful trait gene is selected from a large number of crossed progenies using a DNA marker that is a DNA sequence that serves as a marker of the location of the specific useful trait gene on the genome. In the method, the crossed progeny is analyzed when it is an infant plant using a DNA marker to effectively shorten the time required for the breeding.

Genomic selection is a technique in which a prediction formula is created from a phenotype and genomic information obtained in advance to predict the property from the prediction formula and the genomic information without evaluating the phenotype, and is a technique that can contribute to improving breeding efficiency. The term “new breeding techniques” is a general term for breed improvement (breeding) techniques that combine molecular biological techniques. Examples of the new breeding techniques include cisgenesis/intragenesis, oligonucleotide-directed mutagenesis, RNA-dependent DNA methylation, genome editing, grafting on a GM rootstock or a scion, reverse breeding, agroinfiltration, and seed production technology (SPT). The genome editing technique is for converting genetic information in a sequence-specific manner, and it is possible to delete a base sequence, substitute an amino acid sequence, introduce a foreign gene, and the like using the technique. Examples of the tool include sequence-specific genome modification techniques such as a zinc finger nuclease capable of sequence-specific DNA cleavage (Zinc-Finger, ZFN), TALEN, CRISPR-Cas9, CRISPER-Cpf1, Meganuclease, and CAS9 Nickase and Target-AID created by modifying the aforementioned tools.

Examples of the above-mentioned plants include plants listed in the database of the registered genetically-modified crops (GM Approval Database) in the electronic information site of International Service for the Acquisition of Agri-biotech Applications (ISAAA) (http://www.isaaa.org/). More specific examples are herbicide-tolerant plants, pest-resistant plants, disease-resistant plants, plants modified in the quality (for example, with increase or decrease in the content or change in the composition) of the products (for example, starch, amino acids, and fatty acids), fertility trait-modified plants, abiotic stress-tolerant plants, and plants modified in the trait related to the growth or the yield.

Examples of the plants to which herbicide tolerance has been imparted are described below.

The mechanism of obtaining tolerance to a herbicide is reduction in the affinity between the agent and its target, rapid metabolism (decomposition, modification, and the like) of the agent by an expressed enzyme that inactivates the agent, or inhibition of incorporation or translocation of the agent in the plant body.

Examples of the plants to which herbicide tolerance has been imparted by genetic engineering technique include plants to which tolerance has been imparted to 4-hydroxyphenylpyruvate dioxygenase (hereinafter abbreviated as HPPD) inhibitors such as isoxaflutole and mesotrione, acetolactate synthase (hereinafter abbreviated as ALS) inhibitors such as imidazolinone herbicides containing imazethapyr and sulfonylurea herbicides containing thifensulfuron-methyl, 5-enolpyruvylshikimate-3-phosphate synthase (hereinafter abbreviated as EPSP) inhibitors such as glyphosate, glutamine synthase inhibitors such as glufosinate, auxin herbicides such as 2,4-D and dicamba, and oxynyl herbicides containing bromoxynil. Preferable herbicide-tolerant transgenic plants are cereals such as wheat, barley, rye, and oats, canola, sorghum, soybeans, rice, rape, sugar beet, sugar cane, grapes, lentils, sunflowers, alfalfa, pomaceous fruits, drupes, coffee, tea, strawberries, lawn grass, tomatoes, potatoes, cucumbers, and vegetables such as lettuces, and more preferable herbicide-tolerant transgenic plants are cereals such as wheat, barley, rye, and oats, soybeans, rice, vines, tomatoes, potatoes, and pomaceous fruits.

In the above-mentioned weeds, mutations within the species are not particularly limited. That is, the weeds include weeds having reduced sensitivity to a specific herbicide. The reduced sensitivity may be attributed to a mutation at a target site (target site mutation), or may be attributed to any factors other than the target site mutation (non-target site mutation). Examples of the factor of the reduced sensitivity due to a non-target site mutation include increased metabolism, malabsorption, translocation dysfunction, and excretion to out of system. Examples of the factor of the increased metabolism include the enhanced activity of a metabolizing enzyme such as cytochrome P450 monooxygenase, aryl acylamidase, esterase, or glutathione S-transferase. Examples of the excretion to out of system include transport to the vacuole by an ABC transporter. Examples of the weeds having reduced sensitivity due to a target site mutation include weeds having any one of, or two or more of the following amino acid substitutions in the ALS gene. Ala122Thr, Ala122Val, Ala122Tyr, Pro197Ser, Pro197His, Pro197Thr, Pro197Arg, Pro197Leu, Pro197Gln, Pro197Ala, Pro197Ile, Ala205Val, Ala205Phe, Asp376Glu, Arg377His, Trp574Leu, Trp574Gly, Trp574Met, Ser653Thr, Ser653Thr, Ser653Asn, Ser635Ile, Gly654Glu, and Gly645Asp. Similarly, examples of the weeds having reduced sensitivity due to a target site mutation include weeds having any one of, or two or more of the following amino acid substitutions in the ACCase gene. Ile1781Leu, Ile1781Val, Ile1781Thr, Trp1999Cys, Trp1999Leu, Ala2004Val, Trp2027Cys, Ile2041Asn, Ile2041Val, Asp2078Gly, Cys2088Arg, Gly2096Ala, and Gly2096Ser.

Similarly, as an example of the weeds having reduced sensitivity due to a target site mutation, PPO inhibitor-resistant weeds having one or more mutations selected from an Arg128Leu mutation, an Arg128Met mutation, an Arg128Gly mutation, an Arg128His mutation, a Gly210 deletion mutation, and a Gly399Ala mutation in PPO. The word “PPO” means protoporphyrinogen oxidase. Weeds usually have PPO1 and PPO2 in PPO, and the above-mentioned mutations may be present in either PPO1 or PPO2 or in both. The case where weeds have the mutations in PPO2 is preferable. For example, the word “Arg128Met” means that the mutation is present in the 128th (the number is standardized with PPO2 of Amaranthus palmeri) amino acid. In PPO2 of Ambrosia artemisiaefolia, the mutation corresponds to a mutation in the 98th amino acid (Weed Science 60, 335-344) and is known as Arg98Leu. In this case, Arg98 is equivalent to Arg128 according to the present invention. The Arg128Met mutation and the Arg128Gly mutation in the PPO of the weed to be controlled in the present invention are known in Amaranthus palmeri (Pest Management Science 73, 1559-1563), the Arg128His mutation is known in Lolium rigidum (WSSA annual meeting, 2018), and the Gly399Ala mutation is known in Amaranthus palmeri (WSSA annual meeting, 2018). In the present invention, the above-mentioned reported resistant weeds are particularly effectively controlled, but particularly effectively controlled weeds are not limited thereto. That is, other weeds having the amino acid mutation are similarly controlled. Not only Amaranthus palmeri having an Arg128Leu mutation, an Arg128Met mutation, an Arg128Gly mutation, an Arg128His mutation, a Gly210 deletion mutation, or a Gly399Ala mutation, but also, for example, waterhemp having the above-mentioned mutation, Ambrosia artemisiaefolia having the above-mentioned mutation, Lolium rigidum having the above-mentioned mutation, Lolium multiflorum having the above-mentioned mutation, and Euphorbia heterophylla having the above-mentioned mutation are effectively controlled.

Similarly, examples of the weeds having reduced sensitivity due to a target site mutation include weeds having an amino acid substitution such as Thr102Ile, Pro106Ser, Pro106Ala, or Pro106Leu in the EPSP gene. In particular, Eleusine indica, Lolium multiflorum, Lolium rigidum, Digitaria insularis, waterhemp, Echinochloa colona, and the like which are resistant to glyphosate and have one or both of the mutations are effectively controlled. Similarly, examples of the weeds having reduced sensitivity due to a target site include weeds having increased copies of the EPSP gene, and Amaranthus palmeri, waterhemp, Kochia scoparia, and the like which are resistant to glyphosate and have the mutation are particularly effectively controlled. Conyza canadensis, Conyza smatrensis, and Conyza bonariensis which are resistant to glyphosate in which an ABC transporter is involved are also effectively controlled.

In the cultivation of a crop according to the present invention, plant nutritional management in general cultivation of a crop can be performed. The fertilization system may be based on Precision Agriculture or may be conventionally uniform one. In addition, a nitrogen-fixing bacterium or a mycorrhizal fungus can be inoculated in combination with seed treatment.

EXAMPLES

Hereinafter, the present invention will be described by Examples, but the present invention is not limited thereto.

First, evaluation criteria are shown for the herbicidal efficacy and the crop injury described in Examples below.

[Herbicidal Efficacy and Crop Injury]

In the evaluation of herbicidal efficacy, the efficacy is defined as “0” if the state of budding or growth of test weeds indicates little or no difference compared to that in the case of no treatment at the time of the investigation. The efficacy is defined as “100” if test weeds are completely killed or the budding or growth of test weeds is completely prevented. Hence, the efficacy is classified as “0 to 100”.

In the evaluation of crop injuries, the injury is defined as “harmless” if a harmful effect is little observed. The injury is defined as “small” if a mild harmful effect is observed. The injury is defined as “medium” if a moderate harmful effect is observed. The injury is defined as “large” if a severe harmful effect is observed.

Example 1

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) are sown in a plastic pot. On the same day, a mixed spray liquid is applied on the soil surface at the spray volume of 200 L/ha so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha and the application rate of ZIDUA (pyroxasulfone 85% water dispersible granule, manufactured by BASF SE) may be 70, 140, or 280 g/ha (1, 2, or 4 ounces/acre). Then the weeds are cultivated in a greenhouse, and at 7 days after the application, soybeans are sown. Fourteen days after seeding the soybeans, the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Example 2

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) and soybeans are sown in a plastic pot. On the same day, a mixed spray liquid is applied on the soil surface at the sprayed amount of 200 L/ha so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha and the application rate of Sharpen (saflufenacil 29.7% wettable powder, manufactured by BASF SE) may be 73 ml/ha (1 fluid ounce/acre). Then the weeds and the soybeans are cultivated in a greenhouse, and 21 days after the application, the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Example 3

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) and soybeans are sown in a plastic pot. On the same day, a mixed spray liquid is applied on the soil surface at the spray volume of 200 L/ha so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha and the application rate of Valor SX (flumioxazin 51% wettable powder, manufactured by Valent U.S.A. LLC) may be 140 g/ha (2 ounces/acre). Then the weeds and the soybeans are cultivated in a greenhouse, and 21 days after the application, the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Examples 4 to 6

Tests are carried out in the same manner as in Examples 1 to 3 except that the soybeans are replaced with corns or cottons.

Example 7

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) are sown in a plastic pot. Then the weeds are cultivated in a greenhouse, and 21 days after the sowing, a mixed spray liquid is applied to the foliage at the spray volume of 200 L/ha so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha and the application rate of RoundupWeatherMax (glyphosate-potassium salt 660 g/L, manufactured by Monsanto Company) may be 2.338 L/ha (32 fluid ounces/acre). The weeds are further cultivated in the greenhouse, and 7 days and 14 days after the treatment, the effect on the weeds is investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Example 8

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) are sown in a plastic pot. On the same day, a spray liquid which is prepared so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha is applied on the soil surface at the spray volume of 200 L/ha. Then the weeds are cultivated in a greenhouse, and 7 days after the application, soybeans are sown, and a spray liquid which is prepared so that the application rate of ZIDUA (pyroxasulfone 85% water dispersible granule, manufactured by BASF SE) may be 70, 140, or 280 g/ha (1, 2, or 4 ounces/acre) is applied at the spray volume of 200 L/ha. Further 14 days after the sowing of soybeans, the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

On the same day, a spray liquid which is prepared so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha is applied on the soil surface at the spray volume of 200 L/ha. Then the weeds are cultivated in a greenhouse, and 7 days after the application, soybeans are sown, and a spray liquid which is prepared so that the application rate of Sharpen (saflufenacil 29.7% wettable powder, manufactured by BASF SE) may be 73 ml/ha (1 fluid ounce/acre) is applied at the spray volume of 200 L/ha. Further 14 days after the sowing of soybeans, the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Example 10

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) are sown in a plastic pot. On the same day, a spray liquid which is prepared so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha is applied on the soil surface at the spray volume of 200 L/ha. Then the weeds are cultivated in a greenhouse, and 7 days after the application, soybeans are sown, and a spray liquid which is prepared so that the application rate of Valor SX (flumioxazin 51% wettable powder, manufactured by Valent U.S.A. LLC) may be 140 g/ha (2 ounces/acre) is applied at the spray volume of 200 L/ha. Further 14 days after the sowing of soybeans, the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Examples 11 to 13

Tests are carried out in the same manner as in Examples 8 to 10 except that RoundupPowerMax (glyphosate-potassium salt 660 g/L, manufactured by Monsanto Company) is additionally used in the application of trifludimoxazin so that the application rate of RoundupPowerMax may be 2.338 L/ha (32 fluid ounces/acre, 1,543 g/ha as glyphosate-potassium salt).

Example 14

Weeds (Amaranthus palmeri, waterhemp, Ambrosia artemisiaefolia, Ambrosia trifida, Conyza canadensis, Chenopodium album, Kochia scoparia, Echinochloa crus-galli, and Setaria faberi) are sown in a plastic pot. On the same day, a spray liquid which is prepared so that the application rate of trifludimoxazin may be 25, 50, 100, or 200 g/ha is applied on the soil surface at the spray volume of 200 L/ha. Then the weeds are cultivated in a greenhouse, and 7 days after the application, soybeans are sown, and 14 days after the sowing, a spray liquid which is prepared so that the application rate of RoundupWeatherMax (glyphosate-potassium salt 660 g/L, manufactured by Monsanto Company) may be 2.338 L/ha (32 fluid ounces/acre) is applied at the spray volume of 200 L/ha. Further 14 days later (28 days after the sowing), the effect on the weeds and the crop injury on the soybeans are investigated. A synergistic weed controlling effect compared to the single use of each compound is confirmed.

Example 15

A test is carried out in the same manner as in Example 14 except that RoundupPowerMax (glyphosate-potassium salt 660 g/L, manufactured by Monsanto Company) is additionally used in the application of trifludimoxazin so that the application rate of RoundupPowerMax may be 2.338 L/ha (32 fluid ounces/acre, 1,543 g/ha as a glyphosate-potassium salt).

Examples 16 to 23

Tests are carried out in the same manner as in Examples 8 to 15 except that the soybeans are replaced with corns or cottons.

Examples 24 to 46

In the case where any crops are used in Examples 1 to 23, tests are carried out in the same manner as in the Examples except that the crops used in the Examples are replaced with crops having a Roundup Ready 2 Xtend trait.

Examples 47 to 69

In the case where any crops are used in Examples 1 to 23, tests are carried out in the same manner as in the Examples except that the crops used in the Examples are replaced with the crops having both a Roundup Ready 2 Xtend trait and a PPO inhibitor-tolerant trait due to foreign PPO having lower affinity for the PPO inhibitor than the endogenous PPO of the crops by genetic engineering.

INDUSTRIAL APPLICABILITY
